people to get around in a way that steps lightly on the environment. we want people to get around in ways that are enjoyable. and that really contribute to what makes san francisco special, such as our wonderful cable cars. but above all, we want to make sure that people can get around the city safely. it's no good to have a great transportation system if people can't get around safely. people need to not only be able to be safe, but to be able to feel safe, and nowhere is that more important than when you're on foot because that is when you're arguably the most vulnerable. it's also how every trip starts and ends. and many trips in san francisco, and we want more of them in between, to be on foot as well because it's a nicer way to enjoy the city. but if we want people to be out and walking, we need them to be safe. we want them to feel safe, and that's what we're here to talk about today. and none of that will happen without great leadership. so, without further ado, happy to bring up our great leader, the mayor of the city and county, ed lee. (applause) >> thank you. thank you, david.
